An image display method executed by a processor comprises displaying a screen including a two-dimensional fundus image of an examined eye and a three-dimensional eyeball image of the examined eye, finding a second region in the three-dimensional eyeball image that corresponds to a first region specified in the two-dimensional fundus image, and displaying a mark indicating the second region in the three-dimensional eyeball image.

An implementation cost of a line-scan optical coherence tomography (OCT) apparatus is reduced by miniaturizing a scanning mirror and using a light source with relaxed requirement in intensity uniformity. The mirror reflects a probe light beam to different parts of a sample for line-scanning the sample. A line-compressing lens compresses the probe light beam's cross-sectional length before the beam reaches the mirror, allowing the mirror to be miniaturized to reflect only the compressed beam. In generating a linear light beam that gives the probe light beam, a cascade of collimating lens, Powell lens and focusing lens generates the linear light beam from a raw light beam of a point source. A slit further filters the linear light beam to remove a peripheral portion thereof such that the linear light beam is substantially uniform in intensity even if an asymmetrical divergent light source is used.

In accordance with one aspect of the present invention, an optical coherence tomography-based ophthalmic testing center system includes an optical coherence tomography instrument comprising an eyepiece for receiving at least one eye of a user or subject; a light source that outputs light that is directed through the eyepiece into the user's or subject's eye, an interferometer configured to produce optical interference using light reflected from the user's/subject's eye, an optical detector disposed so as to detect said optical interference; and a processing unit coupled to the detector. The ophthalmic testing center system can be configured to perform a multitude of self-administered functional and/or structural ophthalmic tests and output the test data.

Method and apparatus embodiments can generate a volume fluorescence image of a tooth. Method and apparatus embodiments can project structured light patterns onto a tooth and generate a contour (volume) image of the tooth surface from acquired corresponding structured light projection images; then acquire one or more fluorescence images of the tooth generated under blue-UV illumination. A composite image that shows fluorescence image content mapped to the generated contour image can be transmitted, stored, modified and/or displayed.

Embodiments of the present invention may be used to perform measurement of surfaces, such as external and internal surfaces of the human body, in full-field and in 3-D. Embodiments of the present invention may include an electromagnetic radiation source, which may be configured to project electromagnetic radiation onto a surface. The electromagnetic radiation source may be configured to project the electromagnetic radiation in a pattern corresponding to a spatial signal modulation algorithm. The electromagnetic radiation source may also be configured to project the electromagnetic radiation at a frequency suitable for transmission through the media in which the radiation is projected. An image sensor may be configured to capture image data representing the projected pattern. An image-processing module may be configured to receive the captured image data from the image sensor and to calculate a full-field, 3-D representation of the surface using the captured image data and the spatial signal modulation algorithm. A display device may be configured to display the full-field, 3-D representation of the surface.

A method for acquiring image data obtains, for an intraoral feature, optical coherence tomography (OCT) data in three dimensions wherein at least one dimension is pseudo-randomly or randomly sampled and reconstructs an image volume of the intraoral feature using compressive sensing, wherein data density of the reconstructed image volume is larger than that of the obtained OCT data in the at least one dimension or according to a corresponding transform. The method renders the reconstructed image volume for display.
